Make it simple for me please

I have searched and there is a little more info than I need right now. I am confused. Simply: I have an XP system, and will soon have a athlon64 3700 socket 939 system. My cflags for everything are as follows:

-march=athlon-xp -msse -3dnow -mmmx -pipe -fomit-frame-pointer

Except for my kernels cause I didn't touch the flags in the Makefile.

1. I want to keep my existing install to work with my new hardware, running 32 bit on a 32 bit kernel. Then I want to do a new install on a separate HDD that's full 64 bit, getting it running smoothly at my leisure. Is it possible to use with my current system as compiled with my 64bit hardware? If not, are there any bery generic 32bit flags I could recompile it to with emerge -e to make it work? (i386?)

2. I think that even if the above is possible, I would have to enable 32 bit emu in kernel, and emerge the emulation libs, right?

3. Or do I have to do a complete reinstall regardless, even if I only want to run 32 bit initially?

4. I think I can handle compiling a kernel for my new hardware.

5. Is all this clear? I'm confused so it might not be.

TIA

1) I think, this should work.
On Windows XP you're using 32bit Mode, so why shouldn't this work on a linux kernel?
If you let your CFLAGS as thy are, your system should work normally.

2) If your kernel is using 32bit, this should work. You don't need an emulation

But I'm no expert at this point. You can try it or wait till somebody else repsonds.

The cpu does the "emulation" for you when running a 32bit system. You only need a 32bit emulation libraries when running a 64-bit system because 32bit software can't bind to 64bit libraries.

So you can just compile a new kernel with drivers for the new hardware, replace all hardware and continue to work as normal.

If not, are there any bery generic 32bit flags...

LOL! Baseball been bery bery good to me.

Thanks guys for the quick answer! And the news is good!
